Composite Vector Mesons from QCD to the Little Higgs

We review how the ρ meson can be modeled in an effective theory and discuss the implications of applying this approach to heavier spin-one resonances. Georgi's vector limit is explored, and its relationship to locality in a deconstructed extra-dimension is discussed. We then apply the formalism for ρ's to strongly coupled theories of electroweak symmetry breaking, studying the lightest spin-one techni-ρs resonances. Understanding these new particles in Little Higgs models can shed light on previously incalculable, ultraviolet sensitive physics, including the mass of the Higgs boson
